  • 0

require_once does not seem to work. I am trying to use Zend libraries to send mail but something does not work. I am using my web hosting server provider so I have to put the libraries in a subdirectory (without installing any framework).

// $path= dirname(__FILE__)."/ZendLibrary:".get_include_path() ;
$path= "./ZendLibrary".PATH_SEPARATOR.get_include_path() ;
set_include_path($path);
//echo $path ;

echo "Spot 0" ;
require_once 'Zend/Mail.php';
echo "Spot 1" ;

I got the “Spot 0” message but I don’t get the “Spot 1” message. I have selected only two Zend libraries:

 ZendLibrary/Zend/Mail/* (directory)
 ZendLibrary/Zend/Mime/* (directory)
 ZendLibrary/Zend/Mail.php (script)
 ZendLibrary/Zend/Mime.php (script)

ZendLibrary is a folder in the same directory where my script is. What could happening?

UPDATE#1:

My problem is that the code stops working right when I run require_once. It does not echo “Spot 1” message. I have tried absolute paths for set_include_path, I have tried to load a .php library script without internal require_once statements, but nothing makes it work. As my test is run from a web hosting site in the Internet I don’t have access to logs!.. or do I?

$path= realpath(dirname(__FILE__).'/ZendLibrary').PATH_SEPARATOR.get_include_path() ;
// $path= "./ZendLibrary".PATH_SEPARATOR.get_include_path() ;
set_include_path($path);

    Answer:

    My ISP (web hosting too) has a setting to disable require_once. I was able to setup a Unbuntu virtual machine on VirtualBox and set up a web server. I copied the content of my test web site in my Unbuntu and find out that require_once does work as expected !!! That may explain why the server-side include did not work for me either. The following was a usefull check, that indicated me the file was in the expected place.

    $file = 'ZendLibrary/Zend/Mail.php'; 

if ((!is_file($file)) or (!is_readable($file))) 
   die("File does not exists or is not readable.");

    Now I have to find out why it is disabled, how to enable it, or just switch web hosting company. Update: I had to pay $20 dolars a year more for the provider to enable PHP (in this case to be able to include).

    This site can tell you more about it.
